White Castle will roll out the square burgers at locations in the Big Apple on Jan. 1 as an alternative to their regular menu. White Castle’s decision to go veggie answered the prayers of leaf-eaters while also sparking outrage among meat lovers.

“I feel kind of betrayed about this new veggie thing if you know what I mean,” White Castle patron Mario B. told the Post while visiting a location in Midtown. “This is a classic burger, American food. This veggie thing is trying to keep with the times, but White Castle is classic.”

The miniature veggie patties are provided by the popular Dr. Praeger brand and come with a choice of honey mustard, ranch, or sweet Thai sauce, according to Grub Street. But Vegans beware — everything is safe to eat for them besides the bun, which is not technically vegan, according to White Castle’s Twitter page.

The sliders range between 150-270 calories, depending on the flavor. The healthiness of taking the veggie route gets thrown out the window though when compared to the Original Slider, which is 140 calories without cheese and only 160 with it.

The longstanding fast food chain claims that each burger will be “chock full of lots of vegetables like carrots, zucchini, peas, spinach, broccoli, and more.”

But fast food lovers were already pumping the brakes on the groundbreaking new menu item before even getting a chance to have a taste.

“There’s only one reason I come to White Castle,” said Peter Rosado. “And a new veggie burger doesn’t entice me to come.”

“I’m not a man if I don’t eat meat for Petes sake,” another diner added.

But what everyone seemed to be really scratching their heads about was whether or not the veggie slider would be a healthier choice when the munchies strike.

“It surprises me definitely that White Castle is trying to keep up with trends,” Osmund Tønnesland said outside the 38th street and 8th avenue location. “I probably wouldn’t use it as a ‘healthy alternative’ though, this is still a pretty unhealthy place.”

“I personally wouldn’t serve the new veggie burger to my kids,” said an anonymous diner. “I mean, how much more healthy is that than the original burger?”

The announcement that White Castle would be offering a veggie slider also made waves on Twitter — where people voiced their opinions on the leafy alternative.
